The excavating wheel assembly includes at least one excavating wheel which is angularly disposed with respect to the direction of travel to form an excavation and has digging surfaces on the forward extending end of the excavating wheel. The wheel forms an excavation wider than the following portion of the system. A supporting and housing apparatus rotatably supports the excavating wheel means from the vehicle. Apparatus is provided for raising, lowering and/or tilting the supporting and housing apparatus to position the excavation wheel assembly to thereby vary the excavation. The excavation wheel is provided with means for positively moving the walls of a plurality of buckets between material receiving and material discharging positions.
